gwuentor Joseph Beh/e Patented Mar. 18, 1930 UNITED STATES PATENT JOSEPHIBEELE, OF DALLAS, TEXAS, ASSIGNOR TO THE MUBRAY OQMIPANY,;OF DAL- LAS,TEXAS, A CORPORATION OF TEXAS METHOD OF FINISHING GOTTON.GIN' BIBSApplication filed January 10, 192.9. s rial No. 331,467.

This invention relates to new and useful improvements in methods offinishing cotton gin ribs.

It is important that the ribs used in cotton gins be properly finishedand sized so that when they are assembled in the gin they will becorrectly spaced and will present a smooth working face.

WVhere the ribs are ground by hand it is difficult to get each rib tothe same gauge and the results depend largely upon the skill of theworkman.

The main object of the invention is to carry the ribs through a seriesof successive grinding operations, whereby each rib is ground to adefinite gauge and each rib is thus given substantially the samecurvature.

A further object is to devise a method whereby an unskilled workman mayexpeditious grind the ribs and also whereby oversizing or under-sizingis prevented.

The invention will be more readily understood from a reading of thefollowing specification and by reference to the accompanying drawing inwhich a diagrammatical view depictin the devices used in carrying outthe method is shown.

A gin rib has a foot at each end and these feet are connected by areduced shank or body. The body of the rib is curved to suit therequirements. If the feet are properly gauged they may be placed side byside and the saw spaces between the bodies will be correct, provided thebodies have been ground to the proper gauge.

In the drawing I have indicated five posi tions or stations, eachindicating a separate operation. The rib is first brought to station No. 1 and when removed from station No. 5 it is finished and ready formounting in the gin, provided the screw holes have been previouslvdrilled in the feet.

The ribs are cast and while comparatively smooth require grinding andgauging. The ribs are placed on a moving carrier 10 at station No. 1 andcarried between two grinding wheels 11, whereby the ends of the feet areground and each rib is thus brought to the same len th.

The ri s are next delivered to station No.

of its feet, then passing said rib between 2 and-passed longitudinallybetween the parallel sides of a pair ,of grinding wheels 12, wherebythesideedge of the feetare ground. The wheels at both stations are adustable so as to be set up to compensate. for, wear.

The ribs are carried from stationNo. -2to station No. 3. Atthe latterStHtiO- l .eflChrib is placed against a form 13 and the. under faces ofthe feet ground by apairof grinding wheels 142. The form limits, themovement of the rib toward the wheels and thusthe, feet are faced to adefinite gauge.

.Each rib as it, leaves station No. 3. is delivered to station No.4Where it is mounted on a support 15 with its working face uppermost.

A grinding wheel 16 mounted on a hanger 17 i 3 is then moved over theface of the rib body and the same smoothly and evenly ground.

The rib is next taken to station No. 5 and clamped in a suitable carrier18. This carrier is moved so that the sides of the body of the rib aremoved longitudinally between a pair of guiding wheels 19. These wheelsare set to grind the body to a predetermined width or gauge.

When the rib is discharged from station No. 5 it is ready to be placedin the gin. Screw holes in the feet may be drilled either before thegrinding or after. This method produces uniform ribs, saves a greatamount of time and permits the use of unskilled labor.

While I have shown and described grinding wheels, it is to be understoodthat any instrumentality suitable for the purpose may be used infinishing the ribs.

What I claim. is:

1. The method of finishing cotton gin ribs which consists in passingeach rib between means for removing material from the ends means forremoving material from the side edges of the feet, then presenting thefeet of said rib to means for removing material from the under faces ofsaid rib feet, then subjecting said rib to means for finishing theworking face of the rib body, and then passing the sides of said ribbody between means for removing material, whereby each rib is finishedand also gau ed as to width and length.

2. The met 0d of finishing cotton gin ribs which consists in passingeach rib transverse- 1y between grinding wheels to finish the ends ofthe feet and to gauge the rib to length, then passing each riblongitudinally between grinding wheels to finish and gauge the sides ofthe feet, then supporting said rib and limiting its application togrinders for dressing the under faces of the feet, then subjecting theworking face of each rib to a grinding wheel, and then finishing thesides of the rib body between a pair of grinding wheels.

3. The method of finishing cotton gin ribs which consists in passingeach rib between means for removing material from the side edges of thefeet thereof to gage the same as to width, and then passing the sides ofthe rib body between means for removing material therefrom to gage saidbody of less width than the feet.

4. The method recited in claim 3, with the additional step of supportingsaid rib upon a form and removing material from the work ing facethereof.

5. The method recited in claim 3, with the additional step of passingsaid rib between means for removing material from the ends of the feetto gage the length of the rib.

In testimony whereof I afiix my signature.
